Because they are monocular you will sometimes see quizzing glasses described as 'monocles'. Some were indeed (even if they have a handle) intended for placing within the eye socket but this term is potentially misleading and 'quizzing glass' or simply 'quizzer' is more likely to be accurate. The word 'manocle' meaning a hand-held lens has also been used but is not a popular term. The gold handle of the example shown on the right revolves and features a central compartment for containing a vinaigrette. Quizzers have also been made combined with watch keys or compartments to keep a lock of hair.
Quizzing glass lenses could be round, oval or oblong. The rims are often faceted, or pinchbeck, or mounted with diamonds, turquoise or imitation stones. The museum has one example made from jet. Occasionally a more elaborate example will have both an inner and outer rim. The handles could be plain or decorative like this or more imaginatively constructed, for example as a series of intertwining loops. Sometimes on close inspection the loops can turn out to be more than they first appeared - a dolphin swallowing its own head perhaps, a Roman harp, or back-to-back Chinese dragons. The handles were generally quite short, some offering barely enough material to get a firm grip although a secure hold could be assisted by the decoration which in some cases, therefore, has to be regarded as semi-functional in its purpose.
Victorian quizzing glasses could be hung from a chain worn around the neck. Many of these were made of cut steel. Sometimes the links of the chain are as decorative, if not more so, than the quizzing glass itself. the use of these devices often had negative associations:
Quizzing: 'The act of mocking by a narrow examination through a quizzing-glass or by pretended seriousness of discourse'.
(Definition from the Royal Dictionary Cyclopedia of Universal Reference by Thomas Wright, 1865).
Like spectacles, quizzing glasses were also provided with their own specially shaped cases.
An early variation on the quizzing glass is the single hand lens, which often folds into a case-cum-handle of tortoiseshell or Mother of Pearl. Some of these are difficult to distinguish from magnifiers. The difference is in the position the device needed to be held, closer to the face in the case of quizzing glasses rather than close to the object being viewed.
The popularity of quizzing glasses waned after 1850 but opticians continued to supply quizzing glasses, now often in colourful plastic frames and mainly marketed for women, until the later 20th century.
